AUGUST FRANK YQUNG, F BUNCETON', MISSOURI.

INDICATOR.

Application filed August 31, 1917.

To all whom it may concern:

Be it known that I, AUoiJs'r FRANK Yooire, a citizen of the United States, residing at Bunceton, in the county ofCooper and State of Missouri, have invented certain new and useful Improvements in Indicators; and I do hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to indicators, and more particularly to an indicator specially designed for use in railway cars for indicating to the passengers the names of 4 the streets or stations as they are approached.

An object of the invention is the provision of an indicator including a pairof rollers or shafts arranged one above the other and an indicator cloth adapted to be moved back and forth between the rollers or shafts by the improved operating arms.

With these and other ob 'ects in View, the invention consists of the novel construction arrangement and combination of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawings, in which:

Figure 1 represents a front elevation of the indicator.

l 2 represents a side elevation thereof, partly broken away.

Fig. 3 represents an enlarged detail view of the spring actuated pawl and grooved. pulleys. partly broken away.

Fig. 41 represents a side elevation of the s in-ing actuated pawl and pulley, partly in section, and

Fig. 5 represents an enlarged detail view of the driving mechanism for the lower shaft of the indicator.

Referring to the drawings in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 8 indicates a suitable base carrying vertically disposed standards 9 and a transversely directed top bar 10 having a substantially U shaped shaft support 11 secured at its web portion thereto and having depending arms 12, supporting the outer ends of the top shaft 18 rotatably mounted -in the arms 12 and in the vertical uprights or standards 9. Between the uprights 9 a sprocket wheel 14 is fixed on the top shaft 13 and cooperates with a chain 15 working over a sprocket 16 on the Specification of Letters Yatent.

lower shaft 17 rotatably mounted between the standards or uprights 9. An indicator cloth 18is secured at its opposite ends to the upper and lower shafts 13 and 17 be tween the uprights or standards 9 and is adapted to travel on and wind upon these shafts in the usual manner.

On one end of the top shaft 13 a ratchet wheel 19 having laterally pro ecting teeth is fixed between one standard 9 and the ad jacent arm 12 of the shaft support 11. A pulley 20 is rotatably mounted on the shaft 13 between the ratchet wheel 19 and the adjacent arm 12 of the supporting member 11 and is provided with two spaced grooves or channels 21 and 22. The pulley 20 and ratchet wheel 19 are retained inspaced relation bythe upper end of a supporting bracket 23 having an aperture. therein receiving the shaft 13 and provided with a pair of spaced arms or shoulders 24 and 38.

The bracket is secured at its lower end to the adjacent vertical standard or upright 9.

The pulley 20 is formed at its periphery with a transversely directed recess 25 in which the pawl or looking member 26 is movable on a bolt 28. The member 26 is provided with a laterally projecting tooth 29 normally retained in engagement with the teeth of the ratchet wheel 19 by the tension of a spring 30 coiled around the bolt 28 and disposed between the member 26 and the outer wall of the recess 25, as clearly shown in Fig. 3. One edge of the tooth 29 is beveled at 31, whereby when said tooth is rotated with the pulley 20 and engages the inwardly curved upper end of the arm 24, it is automatically disengaged from the teeth of the ratchet wheel 19. The pulley 20 is normally retained in the position illustrated in Figs. 1 and 2 by a coil, spring 32 fixed at its lower end to the adjacent standard or upright 9 and secured at its upper end in the outer channel or groove 21 of the pulley 20, as indicated at 23. An operating cord or cable 34 is fixed at one end to an eye or the like 35 fixed in the inner groove 22 of the pulley and extending downwardly over an idler pulley 36 fixed to the adjacent upright 9 and extended to a point conveniently near the motorman, engineer or conductor of the car, whereby when the cable or cord is pulled the pulley 20 is rotated in a counter clockwise direction. On its initial movement, the tooth 29 moves of]? of the end of the arm 24 and the spring 30 carries said tooth into locking engagement with the teeth of the ratchet wheel 19, thus rotating the pulley and ratchet 19 in synchronism in one direction. The pulley 20 is rotated one-half of a revolution when stopped by the engagement of the tooth 29 with the end of the arm 38 of the bracket 23. The tension of the spring 32 carries the pulley back to its operative position after the cable 3 1 is released. It will be understood that while the shaft 13 is being rotated by the locking engagement of the tooth 29 with the ratchet wheel 19, the indicator cloth 18 is being wound upon the top shaft 13 and unwound from the lower shaft 17 traveling in the direction of the arrow, as indicated in Fig, 1. r

When it is desired to move the indicator cloth 18 downwardly to wind upon the lower shaft 17, atsecond cable or cord 40 is'actu- 7 ated, which travels upon a pulley 41 rotatablymounted on the end of the shaft. The

pulleytl is retained in its normal position by a spring 4l2, and the pulley, is provided 'with a tooth not shown, similar to the toothr29 hereinbefore described and adapt ed to cooperate with the teeth of a second ratchet wheel 43 having the teeth directed oppositely from the teeth of the ratchet wheel 19, whereby when the operating cord 10 is pulled the pulley 41, ratchet wheel 43' and the shaft 13 are rotated a direction opposite to that in which the shaft rotates when actuated by pulling the left hand cord or cable 34.

It will be understood that the indicator hereinbefore described is to be inclosed by a suitable casing having an opening through the top wall thereof covered by a plate of transparent material whereby the names of the streets, or stations marked on the indicator cloth 18 are clearly visible to the having forked arms straddling said shaft and disposed between said pulley and said ratchet wheel, said pawl being normally retained out of engagement with said ratchet wheel by contact with one of said 7 arms, th'eother of said arms being adapted to function as a stop for the pawl.
